The tractor is a faithful assistant to a person in many spheres of economic activity.
The very word "tractor" is associated with strength, power and endurance! Today we will tell you about the largest tractors in the world today.
The largest tractor in the USSR
During the Soviet era, a huge industrial tractor was created on caterpillar, which received the attention of the Guinness Book of Records. We are talking about the T-800 bulldozer. It is recognized as the most productive, largest and most powerful in the world.
The giant's length is twelve meters forty centimeters, its height is almost five meters. The mass of the unit is also serious, it is one hundred and six tons. The engine of the bulldozer is "BelAZ" with an intercooler and gas turbine supercharging. Its speed is insignificant - it moves forward at a speed slightly more than ten kilometers, and backward at a speed of fourteen kilometers per hour.
This largest bulldozer with loosening and bulldozer equipment was built by the Chelyabinsk Tractor Plant. The largest bulldozer in the Soviet Union was produced in Chelyabinsk The largest bulldozer in the Soviet Union was produced in Chelyabinsk.
Initially, as conceived by the developers, the tractor was supposed to become an assistant when working with frozen heavy soils and rocks, where explosives are powerless. It was supposed to be useful for large-scale excavation work during road construction. With such an assistant, drilling and blasting is not required, since the bulldozer is able to tear the rock with its weight and fang.
The T-800 fully demonstrated its capabilities during the construction of the South Ural nuclear power plant, as well as during the reconstruction of Magnitka. After labor baptism, the giant bulldozer began to be used where other equipment turned out to be powerless.
The most powerful tractors in history
The tractor is an irreplaceable assistant in many fields of activity. One of the most powerful tractors was created in America in the state of Montana. Its name is "Big Bad", which can be translated as "Big friend".
Who was involved in the design is unknown, but several adventurers developed this huge tractor. The team was led by Ron Harmonn. The width of the tractor is six meters forty centimeters, the height is more than four meters, and the length is eight meters.
Engine power is nine hundred Horse power and the speed is seven miles per hour. The weight of the Big Friend is fifty-two tons. The plow length of this tractor is twenty-five meters, which allows you to cope with work on plantations of any size without much difficulty.
A powerful tractor is the TERRION ATM 7360, manufactured at the St. Petersburg Tractor Plant. It has a capacity of three hundred and sixty horsepower. One of the most popular large tractors in Europe is the Fendt 936 Vario. It is produced by the German company AGCO Corporation. The power of the car varies from three hundred and fifty five to five hundred horsepower, which depends on the engine firmware.
A tractor with a nominal capacity of three hundred and seventy horsepower is produced by Great Britain. Its name is Massey Ferguson MF 8690. The Dutch New Holland T9000 tractor is equipped with a 15-liter engine. Its capacity is five hundred thirty-five "horses". Germany is engaged in the production of Claas Xerion 4500. The power of this tractor is four hundred and eighty-three "horses".
Huge units are produced in America by John Deere. One of the largest giant tractors is called John Deere 8345R and 8360R with a capacity of up to three hundred and sixty horsepower, as well as a John Deere 9R series with a capacity of five hundred and sixty "horses". It is known that John Deere machinery works on sixty percent of all agricultural land on the planet.
One thousand one hundred and fifty horsepower - this is the engine power of the Super Dozer bulldozer. Its full name is KOMATSU D575A-3 SD. The length of the car was a little short of twelve meters. Another powerful machine is the KOMATSU D475A-5 SD, with a capacity of eight hundred and ninety horsepower. There is a bulldozer with a capacity of eight hundred and fifty "horses" - this is the CATERPILLAR D11R / D11R CD.
The largest tractor in the world
A lot of powerful large-sized tractors have been produced. But among them is recognized as the largest in the world. We are talking about a bulldozer that has never been used - this is an ACCO dozer with a capacity of one thousand three hundred horsepower. It was designed by the Italian company ACCO for Libya in the early eighties. The bulldozer was supposed to help in the development of new territories.
In those years, Gaddafi, who was the customer of this giant, was accused of international terrorism, which is why the UN sanctioned trade embargoes for Libya. As a result, ACCO dozer remained in Italy. There he is to this day.
A large tractor is considered to be a "Big Bad" made in America. Its full name is Big Bad 747. The giant was built in 1977 and was intended to work on cotton plantations. He can cultivate an acre of land in a minute.
We remind you that you can buy a tractor in Tashkent in the company website, both in leasing and by transfer.
The company implements the websitetractors from various manufacturers.
Gone are the days when the land was cultivated by peasants manually using various mats and other devices. Currently, the scale of plowed land does not allow for the cultivation of land using only manual labor. And it is not profitable from an economic point of view.
Tractors are widely used in agriculture and in other spheres of activity. A tractor is a universal unit capable of performing a huge number of types of work, for this you only need to change the hitch.
The history of the creation of the giant tractor
Currently, the largest tractor in the world is the Big Bud-747. Oddly enough, but the design of this giant was created back in the distant 1970s by the millionaire Ron Harmon. Ron Harmon is an activist who lived in the state of Carolina, USA. It should be noted that the Big Bud-747 tractor is still working in the fields of its inventor's native lands. A separate American company was involved in the preparation of documents and, in part, the assembly of this unit itself.
The creation of this tractor was not accidental, it was an order of the brothers-farmers Rossi, who live in the state of California. However, the brothers themselves could not finally decide on the goal of acquiring this miracle of technology. But, having moved to Florida, they began to use it to cultivate cotton fields. It should be noted that the transportation of this giant is not an easy task, however, it was completed.
The Big Bud-747 has two frames and eight wheels and has the power to pull a thirty-meter plow with full immersion.
300 thousand dollars is the price of this miracle. The price is quite high, and this is one of the main disadvantages, since you can buy a dozen less powerful copies for this amount.
Specifications
"Big Bud-747" has a height of over 4 meters, a length of almost 9 meters, and a width of 5.5 meters. The weight of the giant with an empty tank is 45 tons. It has a 16-cylinder engine with a volume of more than 24 liters. In order to fill the tractor tank once, you will need 380 liters of combustible fuel! But, despite the impressive characteristics of this monster, the giant tractor is quite quiet in operation.
After 20 years, the giant tractor was transported to its historical homeland, and its function is already changing here. Instead of cultivating the cotton fields he did earlier, the Big Bud-747 is now cultivating the soil with a 25-meter cultivator.
Improving the giant tractor
Of course, over time, it became necessary to "refine" some points, improve the characteristics of the "Big Bud-747". Thus, the Detroit Diesel engine was replaced, having undergone changes, its power was 900 horsepower. The capacity of the gas tank has been increased, which is 567 liters. By special order, the Canadian company has created tires for the giant tractor.
Even after all this time, the Big Bud-747 is constantly on the job, cultivating a huge number of acres of land. To this day, it is a unique mechanism of its kind, which is associated with the enormous cost of its production and large dimensions, as a result of which it is impossible to use it on relatively small plots of land.
It should be noted that many much more powerful and large machines have been created in the world, but in their essence they are combines, excavators or other types of equipment. That is why the American "Big Bud-747" is rightfully ranked first among the giant tractors.
We offer you to get acquainted with the technical capabilities of the most powerful wheeled tractors... Which model is considered the real monster in agriculture? So, welcome, the largest tractor in the world
Big Bud 747 - the world's largest tractor
The largest tractor is the American-made 760-horsepower Big Bud 747. This power is provided by a Detroit Diesel diesel engine (volume - 24.1 liters), working on 16 cylinders. The main drawback of this huge giant is the small tank, which holds only 380 liters. This volume is hardly enough for 10 minutes of work. The Big Bud 747 is equipped with a 6-speed gearbox, the braking system is air. An 8-wheeled machine weighs 45.5 tons, its length reaches 8.2 m, height - 4.2 m and width - 6 m. The model can be aggregated with a plow 30 m wide (plowing depth exceeds 3 m).

Interesting fact: The giant was released in 1977 and is still # 1 in terms of power and size. Its inventor Ron Harmon planned that the car would be mass-produced, but it never came to that. It is worth noting that after 20 years of service, the Big Bud 747 has been refitted. Now it is equipped with a more powerful 900-horsepower engine. The tank was also replaced: the volume of the new one was 567 liters. It is known that today the tractor continues to work in American fields.

"Kirovets" K-9520 is considered the largest Russian tractor
The largest and most powerful domestic model is the Kirovets K-9520, which is produced at the St. Petersburg Tractor Plant. The four-wheel drive tractor was presented at the Agrosalon exhibition in 2009. Agricultural machinery of traction class 9 is equipped with German power unit Daimler AG (volume - 12.8 liters), which produces 516 hp. The fuel tank has a capacity of 1,030 liters. Maximum speed, which the car can develop - 30 km / h. The performance of the hydraulic system of the working equipment is 190 l / min. The model is equipped with a trailed Diablo subsoiler. The width of the Kirovets K-9520 is 2.87 m, the length is 7.35 m, and the height is 3.72 m.

At the moment, almost every country in the world annually hosts an exhibition of agricultural machinery. One of the most significant for Russia was the exhibition of JSC "Petersburg Tractor Plant" in Moscow (2009), which showed the largest domestic tractor"Kirovets K-9520". But, despite its impressive size and specifications, it still does not surpass in quality its American counterpart "BigBud-747", which for more than 30 years has been considered the largest tractor in the world.
What makes these giants special and unique?
Production history
The manufacture of this "giant" was carried out by the American millionaire inventor Ron Harmon, who then worked closely with the design bureau "Northern Manifacturing". In fact, Ron did not expect to create a new super-tractor that would be mass-produced on the assembly line. The "BigBud-747" was designed in a single copy for two brothers-agronomists Rossi, who cultivated cotton in Bakersfield, California in the 70s. To this day, the largest tractor in the world drives through the fields of America and for the entire period of its existence has not been put into mass production. What is most interesting is that for 37 years not a single company in the world has developed a similar technique that would have dimensions and technical characteristics similar to those of the Big-Bud.
What is the largest tractor in the world capable of?
As it turned out, the power of this technique is enough to process about 400 hectares of soil per day. A huge 30-meter plow was attached to the tractor, which is capable of plowing the ground to a depth of 120 centimeters. Such performance cannot be boasted by any modern
Technical features of the American "BigBud-747"
Under the hood of the world hides a powerful 16-cylinder diesel engine with a capacity of 760 horsepower.
Detroit Diesel was involved in the development of this unit. Naturally, the appetite of such a giant was immodest. "BigBud-747" consumed about 65 liters per minute diesel fuel... But in spite of everything equipped with a very small fuel tank(only 567 liters). Thus, full refueling the tractor only lasted for 8-10 minutes. The tractor is aggregated with a 6-speed gearbox. Brake system here, as well as on heavy-duty wagons, air type (on all wheels).
As for the dimensions, the "BigBud-747" is simply striking in its dimensions: the length is 8200 millimeters, the width is 6000 millimeters, and the height is 4200 millimeters. The equipped weight of the tractor is 45.5 tons.
It is worth saying that the tires for the "American" were developed individually by the Canadian company "United Tire Company". By the way, the tire diameter itself is 240 centimeters. Having received such big wheels and the engine, "BigBud-747", was instantly awarded the title of "The World's Largest Tractor."
What's the fate of Big-Bud today?
11 years after using it, in 1988, the Rossi brothers decided to sell this equipment to Willowbrook Farms, which is located in Florida. For 9 years he was constantly engaged in loosening and plowing the soil.
And in 1997, "Big-Bud" passed into the hands of a new owner, and now he is in his small homeland, in the state of Montana. Having got to the new owner, he was slightly modernized and received a new diesel engine with a capacity of 900 horsepower. According to experts, its current cost is about 600 thousand dollars.
To this day, this tractor is in absolutely working condition and still processes and loosens the soil of the fields.
Russian hero - "Kirovets K 9520"
Unlike its American counterpart, the largest tractor in Russia has a slightly less weak engine (516 "horses") and a more modern design. It is also worth noting a new modification of the old series "Kirovtsa" - "K-744R3 M1" with a 428 hp engine. with.
Both tractor models are equipped with the latest technology, and all components are manufactured by the world's leading manufacturers. So, the modernized "K-744R3" is equipped with a turbodiesel engine "MB OM 457 LA" and a German axial piston hydraulic system from the Bosch company. According to the manufacturer, the K-9520 and K-744R3 M1 models have high performance, power, are distinguished by ease of operation and modern external appearance(see photo).
The largest tractor in Russia, the K-9520 series, is the latest development of the Kirovsky plant, which has inherited all the best features of its predecessors: a reliable design, a powerful and economical engine. Indeed, over the past few years, the pace of development of domestic technology has been so high that it is safe to say that Russian tractors will be leading in the entire world market in the next 5-10 years.
Conclusion
So, we examined the technical characteristics of the largest tractor in the world of American origin "Big Bud-747" and the features of the new Russian "hero" "Kirovets K-9520".
The largest tractors in the world are not created for vanity, but for increased productivity. They work in extreme conditions, doing super hard work.
Big Bud-747 - the world's largest tractor
Big Bud-747 from USA is heading. Since 1977 he has been in service. Its 16-cylinder Detroit Diese diesel engine delivers 900 horsepower. with. The dimensions are impressive: 8.8 × 6.3 × 4.2 m, its weight with equipment is 50 tons, the tank holds 3785 liters of fuel.

German Claas Xerion 4500
This model of a large tractor is produced by the largest German company Claas. A unique find of the inventors is the Variable Cab, which can be located in the middle, front or rear. This expands the functionality of the unit. Various functions are controlled using a joystick with 8 buttons.
Due to the fact that all wheels are of the same size, the engine power is evenly converted into tractive effort, and the tractor's weight is equally distributed on both axles. This ensures low ground pressure.
The birthplace of the New Holland tractor of the T9000 series is the USA. It is characterized by such unique engineering solutions:
- large torque reserve diesel engine gas turbine supercharged;
- powerful transmission;
- increased wheelbase;
- high performance hydraulics.
The giant is able to perform deep loosening and any heavy work on soil processing.
This bulldozer, the largest in Europe, was created at a tractor plant in Chelyabinsk and is listed in the Guinness Book of Records. Its length is from attachments more than the world's largest tractor, and only 50 cm less height. The enormous power of the bulldozer allows you to loosen the soil, which even explosives cannot cope with. Thanks to its impressive weight, it destroys any obstacles in its path.
Used in construction and mining. The Ural bulldozer can replace an excavator and a vehicle (it digs and pushes the soil itself). A total of 10 tractors of this series were produced, the last one in 1999.
John Deere 8345R and John Deere 8360R
John Deere's 8345R and 8360R are both row-crop tractors. Engine power - 345 and 396 liters. with. respectively. They are very popular among farmers.
This Japanese crawler armored vehicle, which is deservedly considered the king of quarries, is used in the mining industry. Its serial production began at the very end of the last century. With the help of a blade measuring 7.39 × 3.63 m, the bulldozer moves up to 70 m 3 of rock at a time.
Despite the power and impressive size, heavy tractors and bulldozers are easy to operate and have low noise in operation. Tightness, reduced vibration and sound insulation of the cab, the presence of an air conditioner and on-board computer create all the conditions for a comfortable driver's work.
